# Lazy-loaded content

Canonical HTML: /atlas/lazy-content
Atlas version: atlas-2026-07-28-v1
Category: Rendering and client execution

## Definition

Lazy content is deferred until a viewport, interaction, or application state triggers its retrieval.

## How it works

Deferral saves bandwidth for people but introduces an additional condition before a crawler can observe the content or links.

## How to validate it

Record network requests and DOM mutations while scrolling through fixed checkpoints, and distinguish native image loading from script-driven text insertion.

## Common failure

Infinite scroll without paginated URLs creates content a person can reach but a crawler cannot address, revisit, or cite reliably.
